Description

Membrane press device

The present invention relates to a membrane press apparatus (Membrane press), and more specifically, the lower frame is placed on the upper frame at a constant position of the lower frame is placed through the jig member the coating object is a thermal transfer molding or adhesive molding The present invention relates to a membrane press apparatus improved to achieve thermal transfer / adhesion molding of a coating film material on a molding object.

As is well known, coating film materials of various colors and patterns are coated on the object to be processed such as wood having a non-uniform surface and curved surface by thermal transfer / adhesive molding, for example, doors of furniture or exterior cases of electronic products. Coating film material known as 'Membrane press' to obtain the beauty of appearance by heat transfer / adhesive molding of film coating material of specific pattern on household goods or daily necessities such as tableware, souvenir or tableware A press apparatus is proposed and applied to practical use.

According to such a membrane press apparatus, the molding object to be thermally transferred to the coating film material is always maintained at a constant position on the upper frame and the lower frame is mounted on the lower frame by a plurality of cylinder blocks are placed on the lower frame through the jig member; An upper frame pressurized to maintain airtightness by an airtight member formed of, for example, a hard rubber material provided at the periphery of the lower frame during thermal transfer / adhesion of the coating film material to the placed molding object; It is provided on the lower side of the upper frame is provided with a heater means for softening the coating film material in the state in which the upper frame is lowered and pressurized to the lower frame.

In such a membrane press apparatus, the lower frame has a plurality of exhausts for evacuating air flow downstream of the membrane (or coating film material) so that the coating film material adheres to the molding object in the forming chamber formed upon contact with the upper frame. The ball has a structure formed.

Therefore, in such a membrane press apparatus, the molded object is covered by a jig member on a lower frame which is always held at a fixed position so as to apply hydraulic pressure to a plurality of cylinder blocks after covering the coating film material on the molded object. When the upper frame is lowered, the forming chamber is hermetically formed between the lower frame. When the heater means is operated in such a state that the molding chamber is heated to a high temperature, the coating film material on the molding object becomes flexible, and when the high pressure air flow is supplied into the molding chamber, the coating film material is in close contact with the molding object. In the meantime, if the air flow downstream of the coating film material is rapidly evacuated through the exhaust hole formed in the lower frame, the flexible coating film material is optimally coated on the molding object.

However, according to the membrane press apparatus in which the upper frame is lifted by the hydraulic action of the hydraulic cylinder, the molding object or the pellets for conveying the molding object into the molding chamber has an aspect ratio of 130 cm x 260 cm, for example, in the molding chamber. In general, the pressure of 2-6kg / cm² is set so that the cylinder block must support the upper frame at a pressure of approximately 200 tons to prevent airflow from leaking from the forming chamber formed between the upper frame and the lower frame. do.

Therefore, in the membrane press apparatus employing the lifting method of the upper frame, the pressure load by the cylinder block acts on the lower frame so that the air pressure does not leak from the molding chamber, so that the wear of the cylinder block is increased due to mechanical load. In addition, the cylinder block is vertically eccentric due to the thermal expansion of the heater means, which is generally located below the upper frame, resulting in eccentric wear, thereby deteriorating hermetic adhesion between the upper frame and the lower frame. This causes the vacuum pressure to leak.

Further, according to the heater means employed in such a membrane press apparatus, heating is performed to soften the coating film material for proper coating molding of the coating film material, but a high-pressure airflow for pressurizing the coating film material to be in close contact with the molding object is sufficient. In the case of being supplied unheated, the internal temperature of the molding chamber is low, so that the heating time is considerably longer. Therefore, it is disadvantageous that the heating waiting time for the subsequent molding operation is required once the molding operation is completed. do.

In the high pressure supply to the molding chamber in the acting to coat the coating film material on the molding object (P '), and the heater means 424 also serves to heat the coating film material to be flexible.

Next, the operation of the membrane press apparatus according to the preferred embodiment of the present invention having the above-described configuration will be described in detail.

First, for example, when an operation command is generated from the control panel 16 in a state where the molding object P is placed and mounted on the jig member on the first pellet 20, power is applied to the heater means 424. In addition, under the control of the control means of the control panel 16, an electronic control valve (not shown) provided for a specific heating chamber of the heating chamber 420 formed in the upper frame 14 is opened so that outside air is introduced. Accordingly, the introduced airflow is heated by the heater means 424 while circulating each heating chamber 420 through the chamber pipe 422.

In addition, the first electric motor 26 provided in correspondence with the first ferret 20 is controlled by the control means of the control panel 16 to rotate in a constant direction, and thus the first electric motor. The rotational force of the motor 26 is transmitted to the first shaft 64 via the first chain 28 to rotate the first shaft 64. By rotating the first shaft 64, the first pellet conveying chain 66 of the endless track is rotated in a predetermined direction, thereby transferring the first pellets 20 to the lower frame 12. Such first pellets 20 are smoothly supported by a plurality of rollers 20a, 20b, and 20c guided on the guide frame body 24a.

When the optical sensor 204 installed at the rear end of the first pellet 20 reaches the position of the first proximity sensor 120a during the transfer operation of the first pellet 20, the first proximity sensor 120a is removed from the first proximity sensor 120a. A deceleration position signal is generated and applied to the control means of the control panel 16, and the control means performs a control to decelerate the rotation ratio of the first electric motor 26, and accordingly the first pellet 20. ), The feed rate is gradually reduced. Subsequently, when the first pellets 20 are transported such that the optical sensor 204 reaches the position of the second proximity sensor 120b, the control means of the control panel 16 is configured to control the first electric motor 26. The rotation is stopped to stop the transfer of the first pellets 20, whereby the first pellets 20 on which the molding object is placed are controlled by the feed rate on the lower frame 12 to be positioned.

In this state, the coating film material 36 is supplied onto the molding object P together with the optional coating of the adhesive to the molding object P, and then the molding control panel 16 starts molding. When the command date is generated, the control means of the control panel 16 controls the hydraulic pressure to be applied to the first and second hydraulic cylinders 58a and 58b, and accordingly the first and second hydraulic cylinders 58a, 58b) extends and pushes a portion of the first-fourth pivot shafts 52a-52d of the first-fourth lift leg members 42a-42d, and thus the first-fourth lift leg member ( The lower leg members 46a-46d of 42a-42d are pivoted up with the support of the lowermost fixing members 44a-44d, and the upper leg members 50a-50d are also fixed at the uppermost fixing member 56a. -56d) ascends with support.

In addition, the horizontal lifting level of the first and fourth lifting leg members 42a and 42d is an intermediate position of the first horizontal bar 48a protruded between the first and second lifting leg members 42a and 42b. A second fixing fixed at an intermediate position of the second horizontal bar 48b protruded between the upward cam skirt portion of the first fixing cam 60a fixed to the second and fourth lifting leg members 42c and 42d; It is kept constant by the elevating adjustment member 60 interposed between the downward cam skirt portions of the cam 60b, and the overall elevating operation of the lower frame 12 is stably supported by the elevating guide 62 as well.

Therefore, the whole of the lower frame 12 is raised relative to the upper frame 14 to prevent pressure leakage by the packing 14a between the lower frame 12 and the upper frame 14, The pressure load (approximately 200 tons) during molding applied to the lower frame 12 is the first and fourth lifting leg members 42a-42d that are lifted and rotated by the first and second hydraulic cylinders 58a and 58b. Support is possible by the mechanical structure of).

In that state, the control means of the control panel 16 opens the electronic control valve (not shown) provided for the other one of the plurality of heating chambers 420 formed in the upper frame 14 to the heater means. The high temperature / high pressure air stream heated by 424 is controlled to be supplied to the molding chamber formed between the lower frame 12 and the upper frame 14, and the high temperature air flow and the heater supplied to the molding chamber. By means 424, the coating film material 36 on the molding object P is emulsified, so that the coating film material 36 is coated on the molding object P in close contact.

Subsequently, the control means of the control panel 16 operates a vacuum pump at a predetermined point in time at which the coating film material 36 is emulsified and coated, and the high temperature exists below the coating film material 36 in the molding chamber. The coating film material 36 on the molding object P is more firmly formed by the vacuum adsorption method by allowing the high pressure air stream to be immediately discharged to the vacuum tank side through the exhaust hole formed on the lower frame. The high pressure air flow remaining in the molding chamber is exhausted to the outside through an exhaust system (not shown).

When the molding operation is completed, the control means of the control panel 16 is to release the hydraulic pressure supplied to the first and second hydraulic cylinders (58a, 58b), accordingly the first-fourth lifting leg As the members 42a-42d are folded inwardly, the lower frame 12 is lowered with the support of the elevating adjustment member 60 and the elevating guide 62.

When the lower frame 12 is completely lowered, the control means of the control panel 16 performs the control to reverse the first electric motor 26, the reverse rotation of the first electric motor 26 The first chain 28 is transmitted to the reverse rotation of the first pellet feed chain 66 through the first shaft 64, so that the first pellet 20 of the roller (20a-20c) With support it is withdrawn from the underframe 12.

When the switch member 34 is in contact with the first limit switch 342a while the first pellet 20 is drawn out, the switch body 344a of the first limit switch 342a is connected to the first pellet 20. It rotates in the drawing direction and generates a deceleration position signal and applies it to the control means of the control panel 16. Accordingly, the control means of the control panel 16 reduces the rotation ratio of the first electric motor 26. Control will be performed. Subsequently, when the switch member 34 of the first pellet 20 is in contact with the second limit switch 342b, the switch body 344b of the second limit switch 342b rotates to generate a stop position signal. It is applied to the control means of the control panel 16, the control means of the control panel 16 is to stop the reverse rotation of the first electric motor 26, thereby the first pellets 20 The molding operation for the molding object P on the first pellet 20 is completed while stopping at the fully drawn position.

In this state, when thermal transfer / adhesion molding is required in a state where a subsequent molding object is placed on the second pellet 22, a manual operation command on the control panel 16 or the first pellet 20 The second electric motor 30 is automatically rotated in a predetermined direction under the control of the control means of the control panel 16 when the molding operation is completed, and the second electric motor 30 is rotated when the second electric motor 30 is rotated.
